David,

in your configuration fuse make sure debug is enabled.
look for __config(    )

Subject: [PIC] ICD2 coming out of debug mode


I have a situation where I am trying to develop some code using a ICD2 
debugger.

The code is written in Hi-Tech "C" and using MPLAB V7.41. I have not had 
this problem occur on any of the previous projects.

I can compile OK and download to ICD2. I can run the code and a few 
times I can stop and single step, move the breakpoint and
then run again.

But I am getting numerous errors as below...

ICD0083: Debug:  Unable to enter debug mode.  Please double click this 
message for more information.
ICD0069: Debug:  Unable to run target
MPLAB ICD 2 Ready

If I simply click "Connect" in the debug menu , I can continue to run 
the code and also single step etc but I cannot do this long before the error
appears again. I don't seem to need to program code again into debugger, 
it lets me continue just by selecting "connect".

The oscillator on the target seems ok and MCLR is pulled to +5V via a 
shctky dioide and resistor like in all the other projects that do not do 
this.

Thanks in advance for your help

Regards

David
